概念设计与结构设计的信息集成技术研究

基于实例推理进行产品概念设计，基于制造知识对产品概念设计进行评价，根据评价结果提出设计修改意见，从而指导产品概念设计，获得概念设计的优化解。基于用户定义的特征进行产品特征造型和产品初步结构设计，对产品初步结构设计进行参数化处理，采用提出的双向设计方法进行参数化产品结构设计。基于所提出的信息集成协议，使概念设计获得的结果直接驱动结构设计，自动生成产品的三维装配图，初步实现了产品概念设计与结构设计的信息集成。从而解决了产品并行设计过程中的瓶颈问题，为产品设计过程的信息集成与功能集成打下了良好的基础。

Study of information integration of product conceptual design and structure design

Product conceptual design can be carried out by means of case based reasoning. Product conceptual design can be evaluated based on manufacturing knowledge and modified according to the evaluation result, so optimum resolution can be obtained. Feature modeling of product can be carried out based on user defined feature. Product structure can be dealt with parameter. Parametric structure design can be carried out by means of bi directional design method presented by authors. Product structure design can be driven directly by the result of conceptual design according to the application protocol provided by authors and the 3 D assembly drawing of product can be generated automatically. The informtion integration of product conceptual design and structure design can be implemented. The bottle neck problem in the process of product concurrent design can be solved.
